Q:Help...Need a replacement water pump for my BioCube?
ok before replacing have you cleaned the inside, and if there are air bubbles comming out it is because it is running dry. Basically all biocubes do this, the filter pad is slowing down the water too much, so either rince it well or replace it. Also i would wash out the blue sponge right before the pump as that can hold alot of dirt as well. Then if not add more water. But if you want to replace the pump, try via aqua water pumps. they tend to be the best. owner of the BC 29 and BC 14
Q:We lost power and water during the hurricane, need help with water pump.?
1. you are going to need at least a couple gallons of water in a bucket to re-prime. 2. look for a plug at the top of the pump and remove it. 3. pour water into the plug opening, filling up the pump as much as you can. 4. put plug back in so at least one thread is grabbing. by doing this it will allow air to escape and won't be spraying water everywhere. it is also a good idea to keep your hand on the plug. 5. turn on electricity to pump. 6. when you start to notice pressure re-gaining tighten up the plug so it does not drip. It is also a good idea to have an outside tap on to get air out of the lines. Another thing is, it is a good idea to shut off water to toilets and washing machines before re-starting pump because small debris have a habit of clogging them up. When your pressure is back, drain your toilet and cold water line to your washing machine, flushing all the stuff out until you see nice clear water. Hope I helped and good luck.
Q:why is my water pump keep going on and off only when i use it?
Sounds like a bladder tank issue. The bladder gets potential energy when the pump fills the tank. When you open a faucet for water, the potential energy stored in the bladder will push the water out of the tank without the need of the pump coming on until the tank is almost empty. You should be able to rock the tank when the pump first comes on to see if it is light weight, as it would be when almost empty. If not then there's your problem. When the pump ends its cycle is when the tank will be at its heaviest. Again: The tank should be full when the pump is not running and almost empty just before the pump comes on. The water pressure would behave as you describe if the bladder tank is not functioning properly.
Q:Replacing the water pump in a 2007 Dodge Grand Caravan do I have to do anything with the timing belt/chain?
Depends on the engine size . If the pump is driven by the timing belt then yes , if the pump is driven by the serpentine belt then no .
Q:TDH what units are present in the pump parameters?
In the pump parameters, TDH is the head of President (Ying Chi).The formula is as follows:TDH (Ying Chi) = total head (Ying Chi) = (- water pressure readings + drainage pressure gauge (drainage dynamic head - water head + (drainage pressure gauge - water pressure elevation correction table elevation correction)
Q:Would a Timing Belt break a Water Pump?
bearings in the water pump pulley went out and locked up therefore causing belt to snap
Q:Water pump seized in my car..... what could it seizing cause?
It really depends on the car and how hot it got when it overheated. most likely you will need a new belt and of course a water-pump. Possibly you have cracked a cylinder head or warped it, this mostly occurs on aluminum cylinder heads and is unlikely if cylinder heads are iron.
Q:The efficiency of water pump frequency conversion is very low, why?
There is a running curve for the fan and water pump.Enough is enough
Q:How do I know the pump pressure?
Flow 18 cubic meters / hour, lift 100 meters, power 4 kilowatts.The pressure supplied by the pump is 1.0Mpa, which is 10 kg pressure.Is it a multistage pump?
Q:can i drive my car to a service center 5 miles with a blown water pump?
Probably not because most vehicles use a serpentine belt/drive belt to run the water pump and when the water pump goes the belt will most likely fall off. If you have an interference engine where the timing belt runs the water pump, then you could. It's not recommended, but I would do it if I couldn't do the repair myself.
